Acoustic cavitation and sonochemistry [PDF]
, 2013 Sonochemistry is the use of cavitation for achieving a chemical conversion. When microbubbles are driven in the nonlinear regime, localized extreme temperatures (up to 10000 K) and pressures (up to 1000 bar) can be reached upon collapse, the surrounding ...

Why Sonochemistry in a Thin Layer? Constructive Interference
, 2023 Sonochemistry in a thin fluid layer has advantages of no visible cavitation, no turbulence, negligible temperature changes (≲1 °C), low power transducers, and transmissibility (sound pressure amplification) of ≳106.

Solvent-free sonochemistry: Sonochemical organic synthesis in the absence of a liquid medium
Beilstein Journal of Organic Chemistry, 2017 Sonochemistry, i.e., the application of mechanical energy in the form of sound waves, has recently been recognised for its similarity to mechanochemistry and is now included under the umbrella term of mechanochemistry.

Sonocatalytic carbon dioxide reduction for syngas production over surface‐roughened CuxO catalyst
AIChE Journal, EarlyView.Abstract The transition to a carbon‐circular economy requires efficient technologies for converting CO2 into value‐added chemical feedstocks. Sonocatalytic CO2 conversion has recently emerged as a compelling approach to drive this conversion. Here, we report a surface‐roughened CuxO catalyst for sonocatalytic CO2 reduction in aqueous media, achieving a

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy
Angewandte Chemie International Edition, EarlyView.Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Sonochemistry: science and engineering
, 1999 Sonochemistry is the use of ultrasound to enhance or alter chemical reactions. Sonochemistry in the true sense of the term occurs when ultrasound induces "true" chemical effects on the reaction system, such as forming free radicals which accelerate the ...
